From Wikipedia, the free encyclopedia

Automotive software is a software driving a microcontroller within automobiles. These Microcontrollers are usually specific to Automotive application usually containing integrated Bus Transceivers interfaces for Bus Systems like LIN, CAN, MOST, LAN among others. Currently the automobile manufacturers use a software architecture consisting of different Electronic control units (ECUs), a Gateway and Sensors. The gateway is responsible for deciding which information at a certain ECU or a Sensor should be routed to which other ECU. There are typically 6 different kinds of ECUs:

  • Body ECU for Headlights, Brakelights, Windscreen Wipers, Air Conditioning, Power Windows.
  • Comfort ECU for Seat and Steering Position Adjustment, Seat Heating.
  • Powertrain ECU for Fuel Injection, Battery Recharging.
  • Dashboard ECU for Speedometer, Odometer, Fuel gauge.
  • Extended ECU
